14-50 Can you adjust the distance between the lens of portrait camera and Canon 60D? There are experts to guide how to use it well, thank you.

You said 50 1.4, right? No 14-50, my friend.

50 1.4 means that the maximum aperture of the focal length 50 is 1.4, which is the focus of the portrait. This can't be adjusted by the lens, only the photographer's position can be adjusted, and a larger aperture can be used to achieve the effect of portrait shooting. And if the 14-50 you said really exists, it must be a zoom head, but it doesn't seem to exist! !
